Generate a form letter with WordTemplate, then pass it to WordApplication to have formatting applied based on the user's selections.

This demo's template document is in the format of a standard form letter.  The recipient and author information is inserted into the document dynamically.  You could also write the letter text and image into the document using WordTemplate.

After the form letter is generated with WordTemplate, the document is passed to WordApplication, which then applies formatting (font, font size, etc) based on the user's selections.
